Engine Repair

  • How does Bar’s Leaks Engine Repair work?

    Engine Repair contains a combination of the best performance additives to repair the most common oil-related problems. Engine Repair restores lost compression and power, reduces noise and oil consumption, while improving the performance of worn cylinders, rings, bearings, and seals.

  • Will Bar’s Leaks Engine Repair clog my oil filter?

    No, Bar’s Leaks Engine Repair does not contain any sticky substances that would clog or damage your oil filter. It works chemically to stop leaks in gaskets and seals.

  • Will Bar’s Leaks Engine Repair work in synthetic oil?

    Yes, Bar’s Leaks Engine Repair is compatible with ALL types of engine oils, including petroleum, synthetic and high-mileage formulas

  • Isn’t Engine Oil Enough?

    Engine oils are generally used to reduce friction between moving parts. In addition to lubricating, motor oil must cool, provide corrosion protection and is a method of removing contaminants. As lubricants degrade, their properties change, leading to increased friction and wear. Over time the natural wear that occurs inside the engine causes reduced oil pressure, loss of compression (power loss), lower fuel mileage, oil consumption (leaks & smoking) and noise (knocking & ticking).

  • Can I add to existing oil?

    Yes, remove engine dipstick and check oil level. If oil is low, remove oil cap and install entire contents of the two chamber bottle. Do NOT overfill. Top off with manufacturers recommended engine oil as needed. Reinstall dipstick and oil cap. Drive/idle engine for 10-15 minutes.

  • If I install more than the recommend amount, will it work faster or better?

    No, we have formulated our product to work best at the suggested dosage amount.

  • What are the dosage recommendations?

    One 16 oz bottle of Bar’s Leaks Engine Repair, part number 1000, treats 4 to 6 quarts of oil.

  • If first application does not completely stop my leak, may I add another bottle?

    Yes, in engines with seriously damaged components, a second treatment may be required. In this case, it is suggested that the oil and filter be changed, and a second application of Engine Repair be added.

  • How long does it take to start working?

    Bar’s Leaks Engine Repair starts working the minute you install and start driving the vehicle. You will usually see results in about 100 miles or two (2) days of driving.

Aging – as something gets older, it doesn’t perform like it did when it was young. It’s a natural process, and one that we can deal with.  A car’s engine ages over time and can lose its efficiency and power. As your engine gains more miles, oil alone can’t do the job. Engines lose their like-new performance over time, but there are ways to deal with the problem — if you know where to look.

Bar’s Leaks Engine Repair helps to stop and prevent these problems, and also extends the useful life of your engine. A car represents a significant investment, and your engine is the heart and soul of your vehicle. Make sure you’re protecting your investment with engine repair from Bar’s Leaks.

  • “Hello, I want to give you a testimony of my experience with Bar's Leaks Engine Repair 2 Part Formula. Six months ago I was having a problem with my 1993 Saturn SL2. It was smoking out of the exhaust. I went to an auto parts store to look for an additive to help reduce the smoke. I decided to try Bar's Leaks Engine Repair 2 Part Formula. It helped. Then, I had a major breakdown of the car's running ability. The catalytic converter had to be replaced, and the mechanic replaced various other components of the emission control system. The car's yearly tag renewal was coming due, which requires the passing of an emissions test, so I took the car to have it tested. When I got to the front of the line, at the point just before entering the test area, and as my car was idling, it began smoking out of the exhaust. I knew then that I was likely in trouble. The car failed so far out of the acceptable standards that it wasn't even close enough to get a one year waiver (which can be obtained if the emissions are within double the standards). The mechanic had changed the car's oil, and Bar's Leaks had not been added. Knowing that Bar's Leaks had reduced the smoking before, I decided to go to a parts store, purchase a bottle, and add it. I also added a bottle of Heet to the gas. The next day, after driving maybe ten miles to the testing station and maybe a few miles around where I live, I had the car tested again. This time it failed, but within range of qualifying for a waiver. I got all my paper work together and went to the place where a waiver is obtained. They tested it again, and it passed! I think that the increased miles driven since adding the Bar's Leaks allowed the additive more opportunity to do its work. In the six months since then, up until I recently changed the oil again, the smoke hasn't returned. That's with one treatment. I've decided to use a bottle of it every time I change the car's oil.”

  • “I have a 1995 Chevy Z71 with 163,000 miles on it. I love this truck, but over the last several months, I've noticed a few drops of oil over each night. I tried another "Leak Stop" product that made the problem worse. I thought about just replacing the engine, but gave Bars 2-part Engine Repair a try. I put the quart in, drove around town and parked it. I placed an aluminum oil catch pan underneath to see if it worked. Guess what...NO OIL!! Thanks Bar's... you saved me several thousand dollars on a new engine. I'll use your product until my truck retires.”

  • “I had a oil leak on my 2000 GMC Somona and since I have 85,000 miles on the truck I used Bar's Leaks Engine Repair. It has been about two weeks now and it has stopped the oil drips on my driveway completely. I think the drips were from my rear main seal. Thanks!”

  • “Absolutely the best investment I could have made for my high-mileage Dodge. Did EXACTLY what it said it would, in UNDER 100 miles. Stopped my noises and knocks, and improved overall performance. Sure saved me alot of money, and I would highly recommend this product to any consumer who is on a tight budget like myself ...Thanks Bar's Leaks!! (Engine Repair)”

  • “Had the oil pan gasket replaced on my 94 Geo Metro and still had a leak. Used the Bar's leak and drove the car to run errands and checked it each time we stopped. No leaks, thank you Bar's.”

  • “I have a 2004 Infiniti G35X with 178,000 miles. I first used Bar's Leaks Engine Repair 2 Part Formula about 4 months ago. I took my car for an oil change and noticed that the car was leaking oil thereafter. My first thought was to take it back to the mechanic to fix the problem that I felt they caused. Until I did some research, read some reviews and came across Bar's Leaks Engine Repair 2 Part Formula. One formula and the issue was solved. I did get another oil change 3 days ago and added a formula again. Rather safe than sorry!!! Thanks Bar's.”

  • “I have a 1989 Jeep Wrangler with 209K miles. It's just starting to knock, and I am always adding oil. I have had mechanics tell me to just run it until it stops. I was advised to try the Bar's Leaks Engine Repair, and so far the knock had subsided and its been over a month now and I have yet to add oil. This stuff is amazing.”
